They seem to know where the food is. One of my neighbors 2 houses down used to have a cat, and fed it on the patio. A family of racoons visited every night for a free meal. The lady at the other end of my 1-block long street fed racoons every night. Here I sit, half way between and I have yet to even see a racoon track in my yard. (Maybe they know how lethal it is to set foot onto my property

.)
